Collecting Protein Biomarkers in Breath Using Electret Filters: A Preliminary Method on New Technical Model and Human Study. [PDF]

open access: yesPLoS ONE, 2016
Biomarkers in exhaled breath are useful for respiratory disease diagnosis in human volunteers. Conventional methods that collect non-volatile biomarkers, however, necessitate an extensive dilution and sanitation processes that lowers collection ...

Natural regeneration of trees in three types of afforested stands in the Taihang Mountains, China.

open access: yesPLoS ONE, 2014
Natural regeneration is the natural process by which plants replace themselves. It is a cost-effective way to re-establish vegetation, and it helps to preserve genetic identity and diversity.

Fault-fluid evolution in the Xitian W–Sn ore field (South China): Constraints from scheelite texture and composition

open access: yesOre Geology Reviews, 2019
Abstract Understanding fault-fluid evolutionary processes is crucial for understanding the genesis of vein-type deposits. Scheelite and quartz are common hydrothermal minerals in W–Sn ore field faults. In the Xitan ore field (Nanling Range, South China), scheelite textural and compositional features were studied and two types of scheelite were ...

Correlation Analysis between Wind Speed/Voltage Clusters and Oscillation Modes of Doubly-Fed Induction Generators

open access: yesEnergies, 2018
Potential machine-grid interactions caused by large-scale wind farms have drawn much attention in recent years. Previous work has been done by analyzing the small–signal modeling of doubly-fed induction generators (DFIGs) to obtain the oscillation ...

Improving Representation of Deforestation Effects on Evapotranspiration in the E3SM Land Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 11, Issue 8, Page 2412-2427, August 2019., 2019
Abstract Evapotranspiration (ET) plays an important role in land‐atmosphere coupling of energy, water, and carbon cycles. Following deforestation, ET is typically observed to decrease substantially as a consequence of decreases in leaf area and roots and increases in runoff.
